[Epidemiological and clinical profile childhood cancers with pleural and pulmonary lesions in the pediatric oncology unit of Treichville University Hospital (Abidjan, Côte d'Ivoire)].

INTRODUCTION

Pediatric cancers are a major public health problem in sub-Saharan Africa. However, they are seldom studied, especially as regards in their extensive forms.

METHODOLOGY

An eight-year retrospective and descriptive study was carried out so as to specify the epidemiological and clinical characteristics of cancers with pleural and pulmonary involvement in children of 0 to 14years of age in the pediatric oncology unit at the University Hospital of Treichville, Côte d'Ivoire (Ivory Coast).

RESULTS

The frequency of pleural and pulmonary involvement in pediatric cancers was 13.8%. Children's average age was 7.2years, with sex ratio at 2.11. Solid tumors were predominant, with a predominance of Burkitt's lymphoma (39.3%) and nephroblastoma (35.7%). The most affected age groups were 10 to 15years (Burkitt's lymphoma) and 0 to 5years (nephroblastoma). Time to diagnosis ranged from 31 and 60days in 40.4% of cases, and time to treatment was at most 30 days, for the overwhelming majority (97.1%) of the children. Chemotherapy was initiated in 67.9% of patients. Hospital mortality was 73.2%.

CONCLUSION

Through this study, the authors established the profile of childhood cancers with pleural and pulmonary involvement. Comparative studies of mortality in pediatric cancers with and without pleural and pulmonary involvement could further underline the importance of early management before dissemination.
